Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the sintering (vitrification) of pigments for painting photographs on the surface of porcelain plates such as partition plates, porcelain plates, glass plates, ceramic plates, etc. The present invention relates to a method for producing a photographic ceramic plate having an exposed surface formed thereon.

[Background Art] Color photographs made by printing on general photographic paper are made by exposing three photosensitive agent layers formed in advance on photographic paper through a photographic original plate whose color has been separated in accordance with each photosensitive layer. The method used is to form an image, develop it in a developer, and then stop the development and desilver it with a fixer. Because it is originally combined with a photosensitizer and has photosensitivity,
and the problem that the coloring agent itself that can be used in the manufacturing process of photographic paper has a limit and oxidizes over time, so the coloring state inevitably changes as time passes.
In other words, there was the problem of "fading" and it was almost impossible to maintain the same color tone for many years, and since the base material was paper, it was difficult to preserve and display it for a long time. The problem was that it was unbearable.

In addition, as a method for displaying photographs on ceramic plates such as ceramic plates or porcelain plates, a photograph is pasted on the surface of a ceramic plate, etc. by printing on ordinary photographic paper or photographic paper itself (extremely thin). A method has been adopted in which this surface is laminated with a type of synthetic resin that is cured by ultraviolet rays to protect the photograph, but this method still has the problems of the above-mentioned photograph taken by printing on photographic paper. 'It was simply a novelty in that the base material for photographic paper was a ceramic plate, etc., but did not solve the above problems.

Next, by screen printing itself, or by using a transfer technique in which the transfer paper printed by screen printing or other printing techniques is transferred to a ceramic plate, and at this time, ink mainly containing decorative pigments is used. According to
Various methods have been proposed in the past in which a photograph or pattern is formed on the surface of a ceramic plate or the like and then sintered (vitrified).

In the case of conventional methods such as these, since pigments for painting are sintered (vitrified) on the surface of a ceramic plate, the coloring of the photograph or pattern is semi-permanent, and the base material is also a ceramic plate. As a result, they can withstand long-term preservation and display, and the above-mentioned problem of ``photographs made by printing on stamps and paper'' has been solved.However, for example, in cases where screen printing is adopted, pigments for painting can be used. Since printing is carried out using ink mainly composed of , there is a problem in that the mesh is clogged by the pigments used for painting, so it is not possible to perform a high degree of halftone dot resolution for photographs or designs, that is, it is not possible to make the mesh of the screen sufficiently small. In addition, when methods such as gravure printing are used, the ink containing the above-mentioned painting pigments does not get on the fine dots and lines.
There is still the problem that it is not possible to perform high-level halftone resolution, and even though it can be put to practical use for simple things like pictures, this method cannot be applied to things that require high resolution like photographs. However, if a photograph were to be displayed on the surface of a ceramic plate using this method, it would have to be extremely expensive, and there would also be the following problems. In other words, in those using these printing methods, it is necessary to use printing ink made by dispersing decorative pigments in a solvent, so it is necessary to reduce the thickness of the printing layer to a certain level or less. Not only is it impossible to do this, but the ink itself, which is made by dispersing painting pigments in a solvent, becomes opaque, and each printing layer is formed as opaque, making it difficult to mix colors and making it difficult to match the desired color. In order to obtain the desired color tone, the number of plates must be increased, and when the number of plates is increased, the solvents of the inks in the printing layers of each color plate interact with each other, especially when a high degree of halftone separation is performed. This problem becomes more noticeable when the proportion of solvent is increased in order to prevent clogging. Moreover, with such printing methods, there is a problem that the printing layer is formed in a raised state, making it impossible to obtain a natural appearance as a photograph. Therefore, the manufacturing process and the equipment used for it are large-scale, and although it is still suitable for mass production, in which the same photograph or pattern is to be displayed on many ceramic plates, it is difficult to produce single items or small quantities. This is not suitable, and in this case there is a problem of further cost increase.

Although it uses a method similar to various printing methods in terms of separation, it is possible to make the halftone dots during this separation as small as the original photographic film allows, improving clarity. The method for producing the resulting photographic ceramic plate involves preparing a plurality of types of painting pigments with different colors, forming a plurality of photographic original plates corresponding to the colors of these painting pigments, and then forming a photosensitive area or a non-photosensitive area. The first step is to form a photopolymer layer on the surface of a ceramic plate such as a ceramic plate, a porcelain plate, a glass plate, a ceramic plate, etc., and a negative film is applied to the surface of this photopolymer layer. or a second one for forming and exposing a light image by the first photographic master of the positive photographic master;
and a third step of dusting and depositing a powdered decorative pigment having a color tone corresponding to the first photographic original plate onto the photopolymer layer which has become sticky at required portions through this exposure;
The fourth step of gradually heating and firing this ceramic plate in a firing kiln, removing the photopolymer in the photopolymer layer by evaporation or incineration, and sintering the painting pigment 4 onto the surface of the ceramic plate is performed as described above. To provide a device in which a color photograph can be sintered and formed on the surface of a ceramic plate by repeating the combination of a pigment for painting and a photographic original plate as many times as the number of combinations. However, due to the limited number of colors available in the pigments used for painting, the reproduction of red colors in particular is poor, and the overall color reproduction is poor when the finished product is viewed as a color photograph. In addition to this problem, since these pigments for painting are originally opaque materials, there was a problem in that color reproduction was not very clear when viewed only with light incident from the surface side.

[Objective of the Invention] An object of the present invention is to provide a method for producing a photograph that can produce a color image with good color reproducibility and comparable to color photographs made by printing on general photographic paper. It is.

[Disclosure of the Invention] The present invention involves preparing a plurality of types of painting pigments having mutually different colors, forming a plurality of photographic original plates corresponding to the colors of these painting pigments, and then forming a photosensitive area or a non-photosensitive area. a first step of forming a photopolymer layer on the surface of a ceramic plate such as a ceramic plate, a porcelain plate, a glass plate, a ceramic plate, etc.;
A second step of forming an optical image on the surface of this photopolymer layer using the first photographic original plate of the negative or positive photographic original plate and exposing it to light; A third step of dusting and depositing a powdered decorative pigment having a color tone corresponding to the first photographic original plate, and a step of gradually heating and firing the ceramic plate in a kiln to form the photopolymer layer of the photopolymer layer. The fourth step of removing the pigment by evaporation or incineration and sintering the decorative pigment 4 onto the surface of the ceramic plate is repeated as many times as the above-mentioned combinations of the decorative pigment and the original photographic plate, thereby printing a color photograph onto the surface of the ceramic plate. In the first invention, in which the sintering process of the pigment for painting is repeated multiple times with the required color plate for the purpose of improving the overall color reproduction as a color photograph, and the yellow The first sintering of the painting pigment is carried out using gold powder as the painting pigment corresponding to the photographic original plate, and the painting pigment of the corresponding color is used for the photographic original plate of the other color plate. In addition to sintering the painting pigment from the second time onwards, the yellow painting pigment is sintered again as needed on the yellow photographic original plate. This invention consists of two inventions.

(Example 1) A first example according to the first aspect of the present invention will be described below. In this embodiment 1, the ceramic plate 1 is a ceramic plate, a ceramic plate, a ceramic plate, a glass plate, etc. In the case of a ceramic plate or a porcelain plate, even if an unglazed one is used, it is like a tile. It is also possible to use a plate with a glazed surface, and more effective results are obtained especially when a ceramic plate is used. In the following examples, the first to fourth steps will be explained regarding an example in which a ceramic plate is used as the ceramic plate 1.
These first to fourth steps are common to the process of sintering the painting pigment by combining each color plate and the painting pigment, and of course, according to the present invention, the same color plate can be used for multiple times of painting. When sintering the pigment for use, the above-mentioned first to fourth
The steps are the same.

First, the first step will be explained. A photopolymer layer 2 made of a photopolymer that makes the photosensitive or non-photosensitive areas sticky is formed on a ceramic plate 1, such as a ceramic plate, by a method such as lamination. Film body 6 as shown in figure (a)
[For example, DuPont's Chromalin film - trade name]
The photopolymer layer 2 of the film body 6 and the polyester film layer 7 are layered on the surface of the ceramic plate 1 using a laminating device 5 as shown in FIG.
is attached as the surface side of the ceramic plate 1, and lamination is performed on the surface of the ceramic plate 1. At this time, the polypropylene layer 8, which was provided as a release paper on the lower surface of the film body 6, is attached to the surface of the ceramic plate 1. The lower surface of the photopolymer layer 2 from which the polypropylene layer 8 has been peeled off is stuck to the surface of the ceramic plate 1, forming one layer 2 of the photopolymer layer 2 on the surface of the ceramic plate 1 (laminating). ).Here, the polyester film layer 7 is used for protection.In addition, as for the photopolymer layer 2, the photopolymer layer 2 is of a type in which the photosensitive area is sticky, or the non-photosensitive area is sticky. Whether to use a type that has a
has a configuration as shown in FIG. 1(b), in which the polypropylene layer 8 of the film body 6 supplied from the roll film 17 is guided by guide rollers 12 and 13 and wound up on the take-up roller 11. The remaining photopolymer layer 2 and polyester film layer 7 are guided by a guide roller 14 and attached onto the ceramic plate 1, and then heated by a heat roller.
The ceramic plate 1 is laminated onto the surface of the ceramic plate 1 by heat-pressure welding between the ceramic plate 15 and the pressure roller 16.

Next, in the second step, the surface is coated with a layer of 7 otopolymer and 2
and polyester film layer 7 on the surface of ceramic plate 1 laminated with polyester film layer 7.
Align and place the photographic original plate 3 of each color plate closely on top of the
Using a vacuum baking frame device 9 as shown in FIG. 2(a), ultraviolet rays are irradiated as shown in FIG. 2(b). Also, whether the photographic original plate 3 is a negative type or a positive type depends on the type of photopolymer layer 2, that is, the type that becomes sticky when exposed to light or the type that hardens when exposed to light. Figure 2(b) shows an example using the latter type, and the dark part of the photographic original plate 3 is the thick hatched part in the figure. If it is 3a,
By irradiating ultraviolet light in the direction of the arrow in the figure,
Only the crosshatched portions 2a of the photopolymer layer 2 become sticky. Furthermore, photo original 3
Needless to say, it is assumed that when color separation is performed, halftone dot separation is performed by simultaneously performing halftone shading and exposure processing.

After the ultraviolet light exposure is completed in the second step in this manner, in the third step, a decorative pigment 4 having a tone corresponding to the first photographic original plate 3 is powder-deposited. That is, after the polyester film layer 7 is peeled off from the surface of the ceramic plate 1 that has completed the second step and the photopolymer layer 2 is exposed, the pigment 4 for painting is applied to a suitable applicator 25 and lightly powdered. The decorative pigment 4 is adhered to the part that has become sticky due to exposure (or non-exposure), and the excess decorative pigment 4 is removed by gently wiping. Here, there are generally two types of pigments 4 for painting, one for underpainting and one for overpainting, and when using a ceramic plate 1 with a glaze already sintered on the surface, such as a tile, the pigment 4 for painting In this example, a ceramic plate is used for the overlay, but in this example, a ceramic board is used for the underpainting.
Of course, you can use the one for overlay. In general, by using the pigment 4 for decoration that has been made into as fine a powder as possible, a better finish can be obtained, and in the present invention, the pigment 4 for decoration is applied in powder form. One of the features is that the thickness of the adhesion layer can be reduced to approximately the diameter of the powder particles of the decorative pigment 4, that is, the thickness of the adhesion layer can be reduced to the extent that the powder particles are lined up in one or two layers. It is something that you have.

After the third step is completed, this is fired in a firing kiln in a fourth step to sinter the decorative pigment 4 onto the surface of the ceramic plate 1, but the firing in the fourth step is as follows: This is carried out in a well-known kiln for pottery and other kilns, and at this time, the temperature inside the kiln is gradually raised to prevent cracks and rupture holes (the photopolymer layer 2 evaporates) on the surface to which the painting pigment 4 is attached. This allows the photopolymer layer 2 to be removed by combustion or evaporation without causing any damage. Of course, for the purpose of obtaining a special effect, rapid heating may be performed to cause cracks or rupture holes to occur on the surface to which the painting pigment 4 is attached. In addition, the temperature inside the kiln is as follows:
The temperature will be raised to 0, about 700 to 850 degrees Celsius, and if the pigment 4 for painting is used for underpainting, an even higher 0 temperature of about 1100 to 1300 degrees Celsius will be used. By firing in the kiln for the required time, the photopolymer layer 2 is completely removed and only the painting pigment 4 is sintered on the surface of the ceramic plate 1 as shown in FIG. This ceramic plate 1 is gradually or rapidly cooled in a firing kiln to form a semi-finished product 26, and the process with this color plate is completed. In the case of this example, since a ceramic plate is used as the ceramic plate 1, it does not cause cracks even if it is not gradually cooled, and it is removed from the kiln while it is still scorching red. It is also possible to take it out.

Thus, when the fourth step is completed, wait for the ceramic plate 1, which is the semi-finished product 26, to cool down to a certain degree, and then perform the steps 1 to 4 on the remaining color plates from the second onwards. It is something. In other words, there are four color photographs: indigo, red, yellow, and ink.
Usually, the first color plate is a plate, the second color plate is a red rice plate, the third color plate is a lead plate, and the fourth color plate is a black plate. Each original plate 3 is prepared, and first, in the first color plate, exposure is performed using the photographic original plate 3 of the plate in the step of the rear cylinder 2 of the first step, and in the third step, powdering with yellow decorative pigment 4 is performed. After the deposition, a fourth step of firing is performed. Next, after this ceramic plate 1 has been sufficiently cooled, it is exposed as a second color plate using a red rice photographic original plate 3 in a second step after the first step, and a third color plate is exposed.
After dusting with the red pigment 4 in the process, the cylinder 4 is fired in the process. By the way, -
In general, there is a problem in the color development of "red" type pigments in painting pigments, so in the first invention of the present invention, for example, the steps of exposure with this red (maron) plate, powder adhesion, and sintering are carried out in two steps. In this case, when the same color plate is used repeatedly to apply dust with the pigment for painting, the pigment for the painting need not be the same, and different types of pigments may be used. good. When the sintering of the pigment for painting with sekihan is completed in this way, the above-mentioned operations are repeated for the third and fourth color plates (indigo and ink) to obtain a finished color product. In addition,
The number of color plates is not limited to the above four, and may be more or less than this.

Here, when using a ceramic plate 1 such as a tile instead of a ceramic plate as the ceramic plate 1, the pigment for painting 4
The final color plate is used as a top plate, and the finished product is obtained when the fourth and final color plate process is completed. Another method for expressing a color photograph is to repeat the first to third steps as many times as necessary for the number of color plates and the required number of color plates, and then repeat the steps in the fourth step. It is also possible to bake the photopolymer layer 2 in advance.
By forming a large number of fine holes in a distributed manner, it is possible to prevent the photopolymer layer 2 and the like from bursting or cracking during sintering.

(Example 2) Next, an example of the second invention of the present invention will be described. This example describes an example in which the photopolymer layer 2 was formed by applying a photopolymer formed as a liquid onto the surface of the ceramic plate 1 instead of using a laminating method. It goes without saying that the method of forming and exposing the polymer layer 2 may be used in the first invention, and the method of forming and exposing the photopolymer layer 2 of Example 1 may also be used in the second invention.

Thus, in this Example 2, as in Example 1 above, assuming that a color photograph is composed of four color plates of indigo, red, yellow, and ink, the following is performed for each color plate. 1st
This is to perform the fourth step. First, in the first step, a photopolymer such as APR resin that becomes sticky or non-tacky in the exposed area when exposed to ultraviolet rays or other light rays is formed as a liquid, and this is applied to the ceramic plate 1. A first step is performed in which a photopolymer layer 2 is formed on the surface of the ceramic plate 1 by coating the surface using an appropriate method. Next, a photographic original plate 3 is set on the fog light device 18 which can be enlarged and reduced as shown in FIG. The photopolymer layer 2 is exposed to light using an optical image formed on the surface of the photopolymer layer 2. In this Example 2, the exposure may be carried out by the contact printing method as in Example 1, and at this time, if necessary, the photographic original plate 3 may be bonded to the photopolymer layer 2 on the surface of the ceramic plate 1. A transparent thin plate is placed on the photopolymer layer 2 to prevent the photopolymer layer from being damaged, and exposure to ultraviolet rays is carried out through this transparent thin plate in the same manner as in Example 1. After this, the third step is performed in substantially the same manner as in the first embodiment.

After that, in a fourth step, this ceramic plate 1 is fired in a kiln. In the second invention, the painting pigment is sintered using each color plate through the above steps. When sintering the painting pigment using each color plate, first, a yellow color plate is used, and the corresponding color plate is sintered. Gold powder is used as a decorative pigment and sintered. After this, if necessary, the yellow color plate and the yellow decorative pigment are combined again to sinter the decorative pigment, and then other The sintering of the pigment for decoration is performed sequentially using color plates, and at this time, the sintering of the pigment for decoration may be performed several times according to the first invention for the required color plate (for example, sekihan). .

(Embodiment 3) FIG. 7 shows a schematic configuration diagram of a third embodiment of the present invention, and the method of misting light onto the photopolymer layer 2 is the same as that of the first and second embodiments. In the case of both of the above embodiments, an actual photographic original plate was used in the second step to optically form a light image on the surface of the photopolymer layer 2 and perform exposure. In this third embodiment, a virtual photographic original is created using digital information strings corresponding to each color obtained by scanning a photograph with an electronic scanner 21, and in the second step, digital information corresponding to the color of the painting pigment at that time is used. Laser scanner 22 for inputting information strings
In this way, the surface of the photopolymer layer 2 is exposed in a light image manner corresponding to a virtual photographic original plate. As described above, the third embodiment differs from each of the above embodiments in that a digital information string is used as a virtual photographic original plate, and in that exposure is performed by the laser scanner 22 using this digital information string. The other points are the same as those of these embodiments, so the explanation will be omitted. Note that the digital information sequence as a virtual photographic original is input directly to the laser scanner 22 as the output of the electronic scanner 21 (color separation, line separation, and quantization operations are performed simultaneously with color plate reproduction).
Alternatively, the digital information string may be temporarily stored in a storage medium and then reproduced and input to the laser scanner 22.

Further, in the third embodiment, the laser scanner 22
Instead, a fine inkjet nozzle is provided, and the adhesive substance is ejected onto the surface of the ceramic plate from the inkjet nozzle, thereby forming a photopolymer layer on the surface of the ceramic plate and exposing it to light. The first and second steps can be omitted, and the spraying from the inkjet nozzle makes it possible to powder-coat the decorative pigment directly onto the adhesive layer formed on the surface of the ceramic plate.

Furthermore, if the above-mentioned laser scanner 22 and inkjet nozzle are configured to perform these scanning operations along the surface shape of the ceramic on which the image is to be displayed, it is possible to perform scanning operations on uneven materials other than flat plates. It is possible to display a photograph on its surface.

[Effect of the invention] The present invention provides a method for forming a photopolymer layer on the surface of a ceramic plate such as a ceramic plate, a porcelain plate, a glass plate, a ceramic plate, etc. A step of forming an optical image using a negative or positive photographic original plate on the surface of this photopolymer layer and exposing it to light, and applying a powdered decorative pigment having a desired color tone onto the photopolymer layer that has become sticky through this exposure. and a step of firing the ceramic plate in a kiln, removing the photopolymer in the photopolymer layer by incineration or evaporation, and sintering the painting pigment onto the surface of the ceramic plate. Since the photograph is made of a ceramic plate, it can be preserved for a long time by being directly attached to a wall or other fixed object for display. In addition to having the effect of making display possible, since the photograph is displayed on the surface of the ceramic plate by sintering the pigment for painting on the surface of the ceramic plate, it is different from the case where the coloring agent itself is a photosensitizer. Not only does this eliminate these problems, but since the pigments used for painting are vitrified through sintering, there is no risk of subsequent oxidation, and the color does not fade during long-term storage, making it semi-permanent. It has the effect of maintaining the initial clear color tone, and since the photopolymer in the photopolymer layer is removed from the surface of the ceramic plate by evaporation or incineration during the process of firing the ceramic plate, the photopolymer layer is removed from the surface of the ceramic plate by evaporation or incineration. The polymer layer does not remain on the surface of the ceramic plate and impair the storage stability of the exposed photograph on the photographic ceramic plate, and from this point of view as well, it has the effect of good storage stability.

Furthermore, the entire process itself is very simple and can be done by anyone without requiring any skill, resulting in high productivity and the ability to manufacture single items or small quantities at a relatively low cost. It is something. Furthermore, when displaying a design with colors similar to a color photograph, anyone can easily display a design with colors similar to a color photograph with clarity and no fading by simply repeating the above-mentioned simple steps. In the present invention, especially when producing a color photograph,
The thickness of the layer of decorative pigment sintered onto the surface of the ceramic plate could be made as thin as possible, allowing the layer of decorative pigment to maintain its transparency, making it easy to mix colors. Therefore, even with a small number of color plates, it is possible to express even subtle colors, and it is possible to express color photographs with good reproducibility. It has the effect of being inexpensive because it does not require many color plates,
It can be put to practical use in a variety of applications, and furthermore, it does not employ the so-called printing method, merely forming a light image on the surface of the photopolymer layer using a photographic original plate and exposing it to light. This has the effect that halftone dot resolution can be made as fine as the film allows, making it possible to produce photographs with extremely high clarity.

Furthermore, in the first invention, the sintering process of the decorative pigment using the required color plates is repeated multiple times, so even if the types of colors of the decorative pigment are limited, the overall color is close to natural. It has the effect of making it possible to obtain color development, with good reproducibility, and to obtain products that are comparable to ordinary color photographs. In addition, in the second invention, gold powder is used as a pigment for painting on a yellow photographic original plate, the pigment for the first painting (1) is sintered, and the pigment for painting on a yellow photographic original plate is sintered. Then, use the corresponding color of the painting pigment to sinter the second and subsequent painting pigments, and if necessary, sinter the yellow photographic original plate again using the yellow painting pigment. Because it is designed to sinter pigments for painting,
The gold powder located in the bottom layer reflects the incident light from the surface side and illuminates the sintered painting pigment in the upper layer from below, increasing the transparency of the design due to the multi-layered painting pigment and improving the color. It has good reproducibility and has the effect of making it possible to obtain products with high commercial value.
